Java EE (Java Enterprise Edition) General Discussion

Hi, i want to call out.println in a jsp function. That is i am using function like this

<%!
void MyFunction()
{
out.println("this is good");
}
%>

This code fails with error message: "out cannot be resolved"

Also i don't want to return value from the function, since i will later call this function recursive and display value at each instant.
Please suggest any solution.
